New Client Reply: Polarization Calibration

Hello Dr. Greisen,

I am sorry to reply late. As I figured out, the AIPS version on our network is 31DEC08 version. In PCAL, I do not have an option for domodel. Also, if I give pmodel=0, the process ends with an error that 'Total intensities must be provided'. Shouldn't it take the intensity values from SU tables? My inputs are as follows:

Thank you,

Akshaya
